The official Muzai (guava) Muzai is guava, and the official Muzai enjoys a good reputation in Chaoshan, so there is a saying in the Records of Chaoshan Famous Products that "Haimen produces a cake, and the official Muzai produces it". Guandai was originally a sandbar formed by alluvial in Hanjiang waters during the Han Dynasty. Mainly with fertile sandy soil, the soil is moist but not damp, and it is easy to disperse when the hands are pinched into a ball. This soil is undoubtedly the most suitable for planting guava, because it is easy to drop fruit in drought, and the water is too much and the fruit tastes weak. In the Qing Dynasty, the planting of Muzi in Guandai reached its peak. Once in Guandai Township, guava trees were planted all over the village roads, fields, ponds and courtyards. The mullet (mullet) in Dongchi Chaoshan is commonly known as mullet, which is distributed in the shallow sea area, estuary, fresh water and the waters at the junction of salt and fresh water along the Chaoshan coast. The mullet is tender in meat, delicious in taste and rich in nutrition. The fish contains 22% protein and 4% fat. As early as more than 3000 years ago, mullet has become one of the high-grade foods of princes and nobles. Among them, the Shantou area is called the mullet in Dongchihu, Guandai, which is the best product. In ancient times, there was a saying that "if you go to Guandai, you have no food, if you go to Shantou, you have no port". It means that if you don't taste the mullet in Dongchi here when you arrive in Guandai, it's like going to Shantou without going to Shantou port city for nothing. Foreign sweet potato, also known as "foreign sweet potato", is mainly sandy soil. Since ancient times, it has been a three-part field and seven-part garden. Therefore, many drought-tolerant crops such as sweet potato, Muzi and wheat are planted. Ocean-edge red-hearted potatoes are famous around Shantou for their reddish skin, orange flesh, moist and soft flesh, and extremely resistant to cooking. In the old days, villagers in Guandai usually stored the freshly harvested red potato in the attic or under the bed and let it ferment for months or even months. After storage, the "ocean-edge red-heart potato" will have small buds at this time (unlike potatoes, sweet potatoes are non-toxic) and taste the best. At this time, the red-heart potato was directly washed and steamed, and the meat inside the peeled potato showed deep orange, moist and soft, as sweet as sucrose, and tasted like a sweet potato. Therefore, in Shantou Port and Xiapeng, people love to say that "foreign sweet potatoes are fake and sweet".
